Elon Musk was born in South Africa. Satya Nadella was born in India. Sergey Brin was born in the Soviet Union. Jensen Huang and Lisa Su were born in Taiwan. Immigration is America’s superpower, and we’re at risk of throwing it away.

The paper asks how oil suppliers might respond to an anticipated long-run decline in global oil demand. The answer: disinvestment is likely to outweigh the “green paradox”, leading to lower extraction in both the short and long-run. New paper by Kellogg restud.com/the-end-of-oil/

Issue #1: The S-curve depends critically on the log transformation. BBBGH use log(x/1000+1); levels (x), log(x+1), and log(x/100+1) give qualitatively different pictures. The divisor isn't innocuous.
